Knee Replacement
Total knee arthroplasty replaces the worn-out cartilage and bone of the knee with metal and polyethylene components to relieve arthritis pain and restore movement.
Overview
Hospital & stay
Procedure details
How it's performed
Under general or spinal anesthesia, the surgeon makes a midline anterior incision over the knee and a medial parapatellar arthrotomy to expose the joint. Cutting jigs guide precise resection of the distal femur, proximal tibia and (if indicated) the posterior patella; the femoral, tibial and patellar prosthetic components are then trial-fitted, balanced for ligament tension, and finally cemented or press-fit into place. A polyethylene insert is locked onto the tibial tray, the wound is irrigated and closed in layers.
Preparation
- 1Pre-operative assessment with bloods, ECG, MRSA screen and anesthetic review.
- 2Dental check to clear any focal infection; treat skin lesions on the operative limb.
- 3Optimise weight, stop smoking, and engage in pre-habilitation quadriceps and hip exercises.
- 4Arrange home modifications: raised toilet seat, walking frame, removal of trip hazards.
- 5Stop NSAIDs and certain anticoagulants per surgical team instructions before surgery.
Recovery
- 1Day 0-1: Stand and walk a few steps with physiotherapy, usually within 12-24 hours.
- 2Days 1-3: Hospital discharge with crutches; range-of-motion and quadriceps exercises begin.
- 3Weeks 1-2: Outpatient or home physiotherapy; wound check and stitch/clip removal at 10-14 days.
- 4Weeks 4-6: Most people walk without aids and resume desk work; driving usually permitted at 6 weeks.
- 5Weeks 6-12: Return to low-impact sport (cycling, swimming, golf).
- 6Months 3-12: Maximal functional recovery; routine orthopedic follow-up.
Before you travel: what the CDC recommends
The U.S. Centers for Disease Control and Prevention publishes guidance for Americans traveling abroad for medical care. These are its recommendations, not ours.
- Check the qualifications of the clinician who will perform the procedure and the credentials of the facility.
- Bring copies of your medical records, including lab and other test results related to your condition.
- Make sure you can get follow-up care in the United States. Care for complications can be expensive and might not be covered by your health insurance.
- Obtain international travel health insurance that covers medical evacuation back to the United States.
- Plan for the possibility of paying out of pocket for additional or emergency care.
- See your own healthcare provider 4–6 weeks before the trip to discuss risks specific to your health.
- Delay air travel for 10–14 days after major surgery, particularly chest surgery, to reduce risks from changes in cabin pressure.

Knee Replacement abroad: frequently asked questions
How much does knee replacement cost abroad?
At clinics listed on xcuro, prices for knee replacement are: India $4,230 to $7,500 (1 clinic); Turkey $13,000 to $14,800 (3 clinics). Final prices depend on your case and are confirmed in writing after a free consultation.
What is the best country for knee replacement?
There is no single best country; it depends on the surgeon, the clinic and how far you are willing to travel. Among clinics listed on xcuro, prices start lowest in India (from $4,230), and Turkey has the widest choice (3 clinics). Compare surgeons' credentials and independent ratings before price.
How much does knee replacement cost in the U.S.?
Typically $32,570, according to CareCredit (New Choice Health data).
How long do I need to stay abroad for knee replacement?
Plan on about 10 days, from arrival to the flight home. Your surgeon will confirm when it is safe to travel.
Will U.S. insurance pay for knee replacement abroad?
Most U.S. health plans do not pay for elective surgery abroad, and cosmetic procedures are not covered at all. The CDC also warns that care for complications after surgery abroad may not be covered, so check your plan before you book.

What the research says about total knee replacement
14 peer-reviewed sourcesTotal knee replacement (total knee arthroplasty) is a well-established treatment for advanced knee osteoarthritis, supported by large registry datasets, randomised trials, and systematic reviews. Long-term pooled analyses suggest that the majority of modern knee implants survive 15 to 25 years, and most patients experience meaningful reductions in pain and improvements in function. Current research compares alignment strategies, robotic-assisted versus conventional techniques, and the factors that influence patient satisfaction, which can be more variable than for hip replacement. Outcomes are shaped by patient factors, implant design, and rehabilitation, so realistic expectations are important. The references below are selected from peer-reviewed meta-analyses, registry studies, and high-quality comparative research.
